Neal Richardson commented on ARROW-11954:
-----------------------------------------
If I read
https://docs.oracle.com/cd/E36784_01/html/E36874/posix-madvise-3c.html
correctly, posix_madvise should be available (on some Solaris system at least),
but we're including that header and it's not there, so maybe we need to use
madvise instead: https://man7.org/linux/man-pages/man2/madvise.2.html
I'm not sure about mremap:
